Clearing the zombies wins the mission; the civilians you save determine your score.
The game includes safe zones and gates. Air strikes can cause civilian casualties, so assess the surrounding population before using them.
A useful review question
After a run, ask which intervention protected people and which merely moved the threat. Treat this as a planning prompt rather than a verified scoring formula.
Victory and score answer different questions
The official description distinguishes eliminating the outbreak from the number of civilians saved. It does not publish a complete scoring equation. This guide therefore does not assign invented point values, multiplier thresholds or a guaranteed maximum score.
Review interventions with a before-and-after note
For a run you want to study, record the event that prompted a response, what you did and what happened afterwards. If the game displays a civilian count at those moments, retain it in a screenshot or note. Otherwise describe what you can observe without inventing a count.
A final score alone cannot tell you which decision helped or hurt. Compare runs with the same map, scenario and relevant settings. Keep the first breach and your response in separate columns, then choose one change for the next attempt.
Air support requires context
The store warns about civilian casualties from strikes. Before using support, inspect the target area and include the civilian risk in your decision. We have not verified a safe-distance rule, blast radius or damage formula; a unit-specific rule needs testing in the current build.
Use the unit comparison worksheet when studying a defensive setup. If you are working with a friend, agree on communication using the two-player co-op guide.
